Background: Ventilator-associated pneumonia (VAP) after tracheal intubation is a major infectious complication in patients in the intensive care unit (ICU), with an incidence of 8-28%. Oral care in the ICU is essential; however, the presence of an intubation tube and restricted mouth opening cause complications. A healthy commensal microflora in the oral cavity resists colonization by respiratory pathogens, and poor oral hygiene may increase the risk for VAP.

The gut microbiota has been implicated in the modulation of food allergies. Building on previous studies on the preventive effects of combining short-chain fructan 1-kestose (Kes) and long-chain fructan inulin (Inu) in food allergies, we investigated their therapeutic effects in an ovalbumin (OVA)-induced food allergy mouse model. Following OVA sensitization, the mice received 5% Kes and Inu, either individually or a combined 2.

Objectives: Since the efficacy of salvage photodynamic therapy (PDT) for locally recurrent esophageal cancer after definitive chemoradiotherapy (CRT) was proven for the first time in an investigator-initiated clinical trial, various reports have supported the clinical utility of PDT for these lesions. However, the clinical trial had limited indications, including a luminal circumference of ≤1/2, maximum longitudinal lesion length of 3 cm, and no invasion into the cervical esophagus, and there have been few reports of treatment outcomes for lesions exceeding the indications used in the investigator-initiated clinical trial. Therefore, this study was performed to assess the outcomes of treating lesions exceeding the above indications.

Less than half of all patients diagnosed with pancreatic ductal adenocarcinoma (PDAC) respond to chemotherapy, and the prognosis of PDAC is poor, which may be mediated by the gut microbiota. We investigated the clinical improvement effects of 1-kestose, a fructooligosaccharide, on PDAC chemotherapy in this single-center, randomized, controlled pilot trial conducted at Fujita Health University Hospital, which enrolled patients with PDAC. The trial included 1-kestose administration and non-administration groups.

Article Synopsis
  • The new Kyoto guidelines offer evidence-based recommendations for diagnosing and treating intraductal papillary mucinous neoplasm (IPMN), emphasizing the role of endoscopic ultrasonography (EUS).
  • EUS is a high-resolution diagnostic tool that allows for detailed imaging and the collection of cyst fluid or tissue samples, making it essential for pancreatic disease diagnosis.
  • Recent studies show that EUS has over 90% sensitivity for detecting mural nodules, making it at least as effective as other imaging methods, while also highlighting the need for skilled endoscopists to ensure objective results.

Colorectal cancer (CRC) is a leading cause of cancer deaths, closely linked to the intestinal microbiota and bile acid metabolism. Secondary bile acids, like deoxycholic and lithocholic acid, are associated with increased CRC risk due to their disruption of vital cellular functions. In contrast, isoallolithocholic acid (isoalloLCA) shows potential health benefits, highlighting the complex role of bile acids in CRC.

Despite the well-known potential health benefits of prebiotics and non-viable probiotics (paraprobiotics) in various animal species, research regarding their use in penguins is scarce. Our study aimed to investigate the impact of a combined administration of prebiotics and paraprobiotics (referred to here as "parasynbiotics") on the gut microbiome and overall health of Magellanic penguins (Spheniscus magellanicus). The parasynbiotics consisted of 1-kestose, which is a fructooligosaccharide comprising sucrose and fructose, and heat-killed Lactiplantibacillus plantarum FM8, isolated from pickled vegetables.
